What is different between battery charger and adjustable dc battery charger?

Product name	Output voltage	Automatic identification battery voltage	Equal/float voltage	Digital display	Output current constant adjustable	Charging mode	Suitable for all kind of lead acid battery
Adjustable dc battery charger	Voltage adjust from 0v-max (v)	Yes	Be set before factory	Yes	Yes	Yes	Yes
Full auto battery charger	Can not adjust	No	Set by the end user	Yes	Yes	Yes	Yes

What is the difference Between Switching power supply and DC adjustable power supply?

Item Product	Switching power supply	DC adjustable power supply
Output voltage	Generally The output voltage is 12VDC 24VDC 48VDC，Narrow range of Output voltage	Can customize any voltage. Such as:0~1000VDC. The output voltage range 0~100% continues adjustable
Output current	If less than 50A generally 10A 15A 20A 25A 30A 50A The output current is not adjustable. But the power with battery interface, the output current can be adjustable within narrow range of Output voltage	Can customize any current. Such as 0~1000A.The output current range 0~100% continues adjustable
Application	Communication engine room	Battery charging,lab and etc.
Output interface	With battery interface (optional)+terminal output	The product of0-200VDC 0-50A variable dc voltage source without battery interface ,only one terminal output
Equal charging & Float charging	Have equal charging and float charging, and can switch automatically	Don’t have equal charging and float charging, and Need manual adjustment.
Display	current and voltage just can switch display in one LED	0-200VDC 0-50A variable dc voltage source of current and voltage display respectively
Machine parallel	Support multiple machines of same specifications parallel use	0-200VDC 0-50A variable dc voltage source can’t support parallel
Communication interface	RS485/232 optional	Without communication interface（If need communication interface,Can consult the factory of HuaYuan, the price is higher）
Input voltage range	Input AC range widely 176V～280V. But can’t make 110V/380V 3 phase input	110/220/380+/-20% is the most wide input range
Appearance	Rack mount type	Desktop and Rack mount type can be customized
Working frequency	160KHz	50/60HZ
